What are the acoustic performance options for interior ACP ceilings?

Interior ACP ceilings can be tailored for acoustics by integrating perforated skins, acoustic cores, and absorptive back-infill. PRANCE offers perforation patterns—circular, slots, or custom shapes—with up to 30% open area. Behind the perforated aluminum skin, a mineral wool or foam core absorbs mid to high frequencies, achieving NRC ratings from 0.6 to 0.9.

Panel edges are sealed with acoustic gasketing to prevent sound leakage around joints. Optional overlay of stretch fabric can further enhance absorption and conceal lighting or HVAC diffusers. For critical spaces—such as auditoriums or open offices—combining ACP panels with a secondary absorbent plenum liner yields superior broadband control.

By modeling room acoustics and specifying the right combination of perforation density, core thickness, and cavity depth, PRANCE delivers ACP ceiling systems that manage reverberation and improve speech intelligibility while retaining the sleek appearance of metal.
